150
13+46= 59
59+87= 146
Round 46 to the nearest ten, which in this case would be 50 because the last number is larger than a 5.
Then add the 1 back in to make it 150.
x^2 +7x +10
when factored becomes
(x+2) (x+5)
the zeros are x +2 = 0, x = -2
x +5 = 0 x = -5
zeros are -2 and -5
Answer:
I'm am pretty sure that the answer is 320. Hope this helps!
